I am sorry that you did not get the email with instructions that you were suppose to get. The more information that you can provide us with such as what exactly you are trying to do with your Slingbox, the better we can assist you. Feel more than free to use Slingbox.com for support as well. Below is a helpful link:

I have a Slingbox 350 and have downloaded Slingplayer for the Web successfully. I open the slingplayer through Safari.

I am having difficulty with getting the remote control visible on my slingbox on my Mac Air. When the video comes on there is a message saying “ Your current input is unconfigured to use remote control. Please use Safari or Firefox to setup or reconfigure your slingbox.”

Cool. So it's just asking you to reconfigure your source. Since that can no longer be done through the website, even though it says to use a browser. Just download the Slingplayer for Desktop if you don't have it. Log in. Then it should prompt you to reconfigure next to the device that you get that error on.

Sling Media have made a real dog's breakfast over this. What the message 'only works with Slingbox M1' means is that you can ONLY view the video stream if you have an M1 (or an M2). But you have to use that app to configure all other Slingboxes. So when you open the app and get the Slingbox Directory your box should have a 'Reconfigure' button. Follow that to set up the video inputs, then you will be able to view the viseo stream on any browser.

Many thanks Alan - I seem to be getting somewhere but not yet at the finish. I have gone through the instructions and even got the Remote control up and the picture but it is stuck in Settings with the Video small in the top right hand corner and the Remote has disappeared. Have tried everything so far. Any ideas?
